VB Decompiler

VB Decompiler is decompiler for programs (EXE, DLL or OCX) written in Visual Basic 5.0 and 6.0 and disassembler for programs written on .NET technology. As you know, programs in Visual Basic can be compiled into interpreted p-code or into native code. .NET assembly always compiled to just in time compilable IL code.

Since p-code consists of high-level commands, there is a real possibility to decompile it into the source code (of course, the names of variables and some functions will not be decompiled). VB Decompiler supports up to 1400 p-code commands and restores source code as much as possible precisely. And after some modifications you may try to compile generated code.

P-Code Example

If a program was compiled into the native code, VB decompiler tries to recover it in the fullest extent possible and provide higher success rate than the similar tools. VB decompiler can help to analyze the program even in this situation as well. It contains a powerful disassembler and emulator. This powerfull engine try to decode most assembler instructions to most likely VB commands. Of course, it fails on some optimizations of assembler code and can't recovery some code. But at this time this is a best way to analyze Native Code applications.

Native Code Example

If a program was compiled to .NET assembly, decompiler will recovery all tables and modules in managed assembly and disassemble all methods, functions and events using IL disassembler. .NET Framework is not needed for decompilation. Decompilation supported on all Windows 32 bit operation systems.

.NET Example

VB Decompiler also decompile all GUI Forms and UserControls presented in file. For technical use decompiler may show offsets of all controls.

Forms Example

In general, VB Decompiler is an ideal tool for analyzing programs and it is perfect if you lose the source code and need to partially restore the project.\

VB Decompiler has 4 different licenses: Lite, Personal, Business and Business with Tracing Features
